ANTIOCH — An Antioch man who died in a fire that burned in a detached garage Thursday morning was not supposed to be there, fire officials said Friday.

Maurice Makinano, 47, was found inside the two-car garage after fire crews responded to the corner of Ninth and J streets just after 6 a.m. The Contra Costa County Coroner’s Office released his identity Friday.

The man is suspected of trespassing and making an unauthorized entry into the garage, spokesman Steve Hill of the Contra Costa County Fire Protection District said. The home’s residents were not aware he was in there.

The fire was burning in all four corners of the garage when crews arrived, Hill said. It did not spread to any of the homes in the area, including the one on the property where the detached garage was located. Medics treated Makinano when they arrived to no avail.

A fire investigator went to a hospital for treatment of a severely cut finger, Hill said.
